Ok (and I missed the part where they are trying to say this is premeditation) so I was going on that basis.
When I took self defense ( a long time ago), not for ccl, I was taught the center mass thing was to STOP the person, not necessarily to kill them... But if that happened, then so be it. The point of center mass was because it is the widest point and easier to hit.
What am I missing?
The necessary, logical consequence of aiming for, and hitting a person at "center mass". In plain language, your objective is to put a bullet through their heart.
